From the project

A collection of Schematics, PCBs and VLSI work on various platforms

This is a small redesign of the Dual Power Supply Complementary Audio Amplifier project for Electronics 1 Lab. This design uses all 1% resistors, so the $ 20k\Omega \, R3 $ and $ R4 $ had to be replaced with $ 2\times 10k\Omega $ Resistors in series. This design was tested and working using the Digilent Analog Discovery 2. The center frequency for this amplifier is still 10kHz.
